APPARATUS FOR FORCING- LIQUID OUT OF RESERVOIRS.

To all whom t may concern:

Be it known that LONARD BARRAS, a citizen of the French Republic, and resident of Paris, France, have invented new and useful Improvements in Apparatus for Forcing Liquid Out of Reservoirs, of which the following is a specification.

This invention relates to an apparatus for distributing gas or steam under pressure for forcing liquids out of vessels. The liquid may be of' any kind and the liuid under pressure is supposed to be air under pressure.

The apparatus is essentially composed of a six-way cock separated in two parts, each part having a piston, one of which serves as motor piston and the other as distributing piston.

In the accompanying drawings the device is shown.

Figure l represents in section the distrib uting device connected with two tanks which contain the liquid. Fig. 2 is a transverse section through the distributing device. Fig. 3 represents in ground plan the connecting links. Fig. 4L shows in section a modified construction of the distributing device. Fig. 5 is a section on line 5 5 of Fig. 4.

According to Fig. 1 of the drawings the distributing device is mounted upon two tanks or reservoirs which may be of any suitable construction, having floats of convenient construction which however have nothing to do with the present invention. It is obvious that the distributing device could work without reservoirs as will be hereinafter explained.

The distributing device is composed of a casing a which is formed of' two separate parts c of which each has three tubular joints b1, b2, b3 and c1, 02, c3 respectively, which are alternately closed or opened by means of' pistons d, e which are connected the one with the other by the connecting links f whose pivots f1, f2 are mounted in the two parts b c respectively of casing a as shown in Figs. l, 2 and 3. Each pivot f1 and f2 has an arm f3 and f4 respectively which arms penetrate into the slots d1, c1 of the pistons d, e, guiding thus said pistons in their casings.

The pistons d, e are of cylindrical shape and they are destined to alternately open, according to the position which they assume7 the orifices of the tubular joints b2 and 53 by the intermediary of the ring-shaped channels cZZ or Z3 and of the tubular joints c2 and c3 by the intermediary of the passages e2 and Specification of Letters Patent.

63, in order to permit the infiow of the air under pressure into the reservoirs, and the escape of the air from said reservoirs. To insure the automatic working of the device the piston which serves as motor has a slightly larger section than the distributing piston. India-rubber rings d4, e4 serve as packings for said pistons. The pivots f1 and f2 are guided in the stuiiing-boxes b4 and c4 which keep the same tight and they are connected at their outer ends by the connecting link f which consists of two links f1 and f2@ whose inner ends are connected by means of a pin 7 fixed upon the link flo and guided in a slot fm of link f2".

The device operates as follows Suppose the valve pistons l and e are in the positions shown in Figs. l, 2 and 3; the air under pressure arrives through the tubular joint b1 of the part of the distributor to How through the channel or openings cl2 and through the tubular joint b2 and pipe r into the reservoir R in opening the valve r1. A second pipe 112 closed by a float valve r3 leads from the reservoir R to the tubular joint c2 of part c of the distributing device. The valve r1 opens under the action of the air pressure and the liquid contained in reservoir R is forced out into the outflow pipe of the reservoir until the valve r3 is automatically opened by the fioat, so that now the air under pressure flows directly through pipe r2 and tubular joint c2 and pushes the valve piston e to the left so that the air under pressure can escape through the channel or openings e2 and the tubular joint c1. The valve piston c in moving to the left 'has taken along the arm f4 which communicating a revolving motion to the pivot f2 revolves the pivot f1 by means of the links flo, )C20 whereby the arm f3 is inversely moved and pushes in its turn its piston CZ in the opposite direction, so that the air under pressure is shut off from reservoir R. Said reservoir being in communication with the outer air through the tubular joint c1 is filled again with liquid until the iioat r3 being gradually lifted by said liquid closes again its valve. The air under pressure fiows now in through the channel Z3 of valve piston (Z and pipe s into the reservoir S, the valve s1 of said pipe opening automatically under the pressure exerted by the air so that the liquid contained in said reservoir S is forced out unt-il the float opens its valve s3 so that the air under pressure can escape through the pipe s2 to iiow into the distributing device by means of tubular joint c3 to push aside the valve piston e whereby the tubular joint e3 is brought in communication with pipe s2 and the air under pressure flows out of Athe device. rlhe reservoir S fills again as described with reference to reservoir R and the arm f* reverses again the piston cl bringing thus the reservoir R again in communication with the supply of air under pressure. Thus, while one of the reservoirs is emptied, the other ills and vice versa, the reciprocating motion of the valve pistons 6l, e being eii'ected lautomatically.

Figs. 4 and 5 represent a modified construction of the device, which is however based upon the same principle. The link connection is dispensed with and the two valves b and c are mounted upon the same axle f1. The casing ZJ which is mounted upon the upper end of axle f1 has three tubular joints b1, Z22, b3 which serve for distributing the air under pressure in connection with the valve piston (Z which has its slot Z1 with which engages the arm f3 projecting from the axle f1. The casing c is mounted upon the lower end of axle f1 and comprises the same parts as described and shown in Figs. l, 2 and 3, that is to say, the tubular joints c1, c2, c3, the valve piston e having the slot el and the arm f4 projecting from the axle f1. The device operates in the same manner as described with reference to Figs. l and 2, with the exception however, that axle fl directly shifts the two valve pistons el, e.

I claim:

A distributing device for gas, steam or air under pressure destined to force a liquid out of reservoirs comprising in combination: a

valve casing with six tubular joints of which three serve for the motor part and the three others for the distributing part of the device7 a piston for each set of three tubular joints having each a central slot and passages at both ends, and seats, each seat engaging the joint at that end of the piston toward which it faces, means for keeping the seats of said pistons tight, an axle for each piston revolubly mounted in the valve casing so that its outer end projects from the same, an arm upon the inner end of each axle engaging with the slot of the corresponding piston, and means for connecting the outer ends of said axles with one another so that the rectilinear motion of one piston is inversely transferred to the other piston, substantially as described and shown and for the purpose set forth.
